HAS-Motion Software Documentation

for example the command below applies the moving rms with a 51 frame window:

moving_rms
/signal_types=analog
/signal_names=emg1+emg2+emg3
/signal_folder=processed
/num_window_frames= 51
;

when reporting rms, it's typically stated as an rms window over a specified time interval of t.

an example of running an rms over a 100 ms (0.1 seconds) window is achieved as:

! moving rms with 100ms window
moving_rms 
/signal_types=analog 
/signal_names=emg1+emg2+emg3 
/signal_folder=processed
! /result_suffix= 
/result_folder=rms 
/num_window_frames= ( 0.1*parameter::analog::rate ) + 1
;

an example of “putting it all together”. first the signal is highpass filtered to remove the dc offset, then lowpass filtered and finally rectified:

! apply a high pass filter with 50 hz cutoff
highpass_filter
/signal_types=analog
/signal_names=emg1+emg2+emg3
/signal_folder=original
! /result_suffix=
! /result_folder=processed
! /filter_class=butterworth
/frequency_cutoff= 50
/num_reflected= 0
/total_buffer_size=100
/num_bidirectional_passes=1
;

! apply a low pass filter with 500 hz cutoff
lowpass_filter
/signal_types=analog
/signal_names=emg1+emg2+emg3
/signal_folder=processed
! /result_suffix=
! /result_folder=processed
! /filter_class=butterworth
/frequency_cutoff= 500
/num_reflected= 0
/total_buffer_size=100
/num_bidirectional_passes=1
;
 
! moving rms with 100ms window
moving_rms 
/signal_types=analog 
/signal_names=emg1+emg2+emg3 
/signal_folder=processed
! /result_suffix= 
/result_folder=rms 
/num_window_frames= ( 0.1*parameter::analog::rate ) + 1
; 

if you are using a version of visual3d older than 4.94, you can use the example here.
